HYDRAULIC SAFETYMaintaining a Safe Work EnvironmentEstablishing a safe work environment in and around your hydraulic equipment is extremely important. The easiest and most effective way to avoid problems is to make sure associates understand their equipment, know how to operate the machines safely, and recognize the dangers if handled carelessly. A few things to be aware of are:

• Pressure: Hydraulic fluid under pressure is dangerous and can cause serious injury. Never look for a leak when unit is under pressure. Using your hand could cause serious injury. A few common ways to encounter hydraulic fluid under pressure include: ▪ Pinhole: Fluid under pressure can cause serious injury. It can be almost invisible escaping from a pinhole, and it can pierce the skin

into the body.

▪ Leak: Keep fittings and hoses tight. Only check and service when not under pressure. Leaking hydraulic fluid is hazardous; in addition to making workplace floors slippery and dangerous, it also contaminates the environment. Before cleaning an oil spill, always check EPA, state, and local regulations.

▪ Burst: Whether due to improper selection or damage, a ruptured hose can cause injury. If it bursts, a worker can be burned, cut, injected, or may slip and fall.

▪ Coupling Blow-Off: If the assembly is not properly made or installed, the coupling could come off and hit or spray a worker, possibly resulting in serious injury. Never operate machine without guards.

• Flammability: When ignited, some hydraulic fluids can cause fires and/or explode.With the exception of those comprised primarily of water, all hydraulic fluid is flammable (including many “fire-resistant” hydraulic fluids) when exposed to the proper conditions. Leaking pres-surized hydraulic fluids may develop a mist or fine spray that can flash or explode upon contact with a source of ignition. These explosions can be very severe and could result in serious injury or death. Precautions should be taken to eliminate all ignition sources from contact with escaping fluids, sprays or mists resulting from hydraulic failures. Sources of ignition could be electrical discharges (sparks), open flames, extremely high temperatures, sparks caused by metal -to -metal contact, etc.

• Mechanical: Hydraulic fluid creates movement, which means some equipment may move. Observe surroundings and equipment at all times.

• Moisture: Do not use in wet or high moisture conditions. • Electrical: Faulty wiring can be an electrical hazard. A regular preventive maintenance program should always include a wiring check. If

applicable, disconnect battery before serving.• Temperature: Because this machine operates at a relatively low pressure, overheating is not common. If surface of tank becomes too hot

to touch by hand (above 130ºF or 55°C), shut off machine and allow it to cool.

Hydraulic FluidOnly use Texaco Rando 46 Hydraulic Oil or compatible fluid like ISO or AW #46 from a brand name manufacturer. Non-compatible fluids could cause damage to unit or serious injury.

CAUTION: NEVER USE YOUR HANDS TO CHECK FOR LEAKS OVER HOSE OR HYDRAULIC CONNECTIONS. USE A PIECE OF CARD-BOARD TO LOCATE A PRESSURIZED LEAK. FOR LOW PRESSURE LEAKS (DRIPS), USE A RAG TO CLEAN THE AREA AND DETERMINE WHERE THE LEAK ORIGINATES.

DANGER: DO NOT TOUCH A PRESSURIZED HYDRAULIC HOSE ASSEMBLY WITH ANY PART OF THE BODY. IF FLUID PUNCTURES THE SKIN, EVEN IF NO PAIN IS FELT, A SERIOUS EMERGENCY EXISTS. OBTAIN MEDICAL ASSISTANCE IMMEDIATELY. FAILURE TO DO SO COULD RESULT IN LOSS OF THE INJURED BODY PART OR DEATH.

WHEEL CLEANER ADJUSTMENT1. Loosen wheel cleaner with 9/16” wrench (Figure 1). 2. Slide cleaner up to the face of the wheel until it touches, but does not dig into the

wheel surface. 3. Re-tighten firmly. Note: Too much interference between the wheel and cleaner will

damage wheel.

WHEEL REMOVAL1. Turn off and unplug machine. 2. Examine back of wheels for built-up debris.3. Remove yarn build-up.4. Place block under machine between wheels.5. Disengage and remove axle pin (Figure 2).6. Remove wheel-securing screw with a 5/16” hex wrench (Figure 2).7. Remove wheel-securing cap. Wheel will slide off. 8. Remove wheel spacer. This should be inspected at regular intervals. 9. Relubricate bearing inside wheel before reassembly.

ADDING OR CHANGING HYDRAULIC FLUID• Change or add fluid when needed; check fluid level if there has been a leak, dam-

aged or ruptured hose, or a loose fitting. Fluid should be level with bottom of tank plug hole (Figure 3).

• To add fluid, unscrew filler port cap from top of machine (Figure 4.1); add fluid through a filter or funnel with a screen to keep fluid clean.

• To change fluid, remove filler port cap. Remove drain plug from side of machine (Figure 4.2). A 2 gallon (8 liter) container will be needed to drain the fluid into. (Fluid will not be removed from hoses.) Regardless of the machine’s straining system, add fluid through a filter or funnel with a screen to keep fluid clean.

INSPECTION OF INTERNAL PARTSVisual inspection of internal parts can be done without draining the tank.

1. Remove two lifting bail eyebolts and the two bolts from the back of the tank.2. Carefully lift tank 3-4’’ (8-10 cm).3. Using a flashlight, inspect the drive chain, hoses, front seal on hydraulic motor, and

suction and pressure line on pump.

4. If service is necessary, follow the procedure for tank removal.
